Okay... Andrea storyline will reveal a lot of things. At the begin of the game you can think she's a stupid slut because she fall in love with the worst man as possible. But some things will be revealed in the next releases. I mean, sometimes in this game things are not what you thought.
Melissa...Okay, she's just a slut, her storyline will be so degradating for her, she's just a Club bartender with drug issues. I'm inspired by real girls. I mean, probably in the future there will a choice between 2 paths (after some events will happen): help her (rehab etc etc) or take advantage (and you coud turn her in a pornstar, yeah there is a path, started with Rain where you can become a porn actor/manager and you can get some girls into porn.- obviously this will depend by the decision you will take about these girls during the game.)I mean, in this game some girls can have really different scenario. I must keep some event to create some scenario and you can't do anything to make some events happens, but your decision can put you in a differente situation. I repeat the Meadow example: you can decide to help her or not. She will reach her goal anyway. but you can have a better or worst relation with her (and with the producer too) and this can help you to get some other events easier. I mean She could help you in the future( for example in soe paths with Martina in 0.8), also the producer could help you (in some other paths in next releases).
What I''m saying is, you would like Melissa not a slut but she is, like in real life. Go on in the game and maybe you'll find the perfect girl(s) for you. In the meantime you can decide if fuck her or not.
